The flag diagnostic_context::some_warnings_are_errors controls whether
to give the message "all warnings being treated as errors". However, when
warnings are buffered and then discarded, this flag is not reset. It turns
out we do not need this flag at all, since we already count explicitly how
many warnings were converted into errors, and this number is kept up to
date for the buffered diagnostics used by Fortran.

    When evaluating a constant expression, the gofrontend would incorrectly
    force each operand to be represented as the resulting type before
    checking if the operation was valid with the untyped constants.
    According to the language specification on constant
    expressions(http://golang.org/ref/spec#Constant_expressions): "Untyped
    boolean, numeric, and string constants may be used as operands wherever
    it is legal to use an operand of boolean, numeric, or string type,

gen_rtx_CONST_VECTOR ensures that there is a single instance of:

       (const_vector:M [(const_int -1) ... (const_int -1)])

for each M, so pointer equality with CONSTM1_RTX is enough.  Also,
HOST_BITS_PER_WIDE_INT == 32 is doubly dead: HOST_WIDE_INT is always
64 bits now, and we always use const_int rather than const_double
or const_wide_int for all-ones values (or any other value that

This patch fixes the issue in PR63304 where we have
functions that are > 1MiB. The idea is to use adrp / ldr or adrp / add
instructions to address the literal pools under the use of a command line
option. I would like to turn this on by default on trunk but keep this
disabled by default for the release branches in order to get some
serious testing for this feature while it bakes on trunk.

As a follow-up I would like to try and see if estimate_num_insns or
something else can give us a heuristic to turn this on for "large" functions.
After all the number of incidences of this are quite low in real life,
so may be we should look to restrict this use as much as possible on the
grounds that this code generation implies an extra integer register for
addressing for every floating point and vector constant and I don't think
that's great in code that already may have high register pressure.

Tested on aarch64-none-elf with no regressions. A previous
version was bootstrapped and regression tested.

Applied to trunk.
